This paper describes a landslide that involves a single family residence near Seattle, Washington in the United States. Remediation of the slide initially involved a heavily anchored, soldier pile and timber lagging wall that would be extremely costly for the homeowner. An alternative remediation using smaller drilled-in-place piles with timber lagging held in-place with several drilled tie-back anchors and lightweight geofoam block backfill was selected. The smaller wall size and cost was feasible because lightweight block geofoam was used as the backfill material. The static and seismic design of the wall, the wall construction, and the cost savings to the homeowner are discussed in this paper. |
